Nano particlesvane diki diki saizi, yakakwirira pamusoro pesimba, uye vane katsika kekungoerekana agglomerate.Kuvapo kweagglomeration kuchakanganisa zvakanyanya zvakanakira nano powders.Naizvozvo, maitiro ekuvandudza kupararira uye kugadzikana kwenano hupfu mune yemvura yepakati yakakosha zvikuru Misoro yekutsvagisa.
Particle dispersion inyaya ichiri kubuda yakagadziriswa mumakore achangopfuura.Iyo inonzi particle dispersion inoreva nzira yekuparadzanisa uye kuparadzira zvidimbu zvehupfu mumhepo yemvura uye yakagoverwa zvakafanana mukati mechikamu chemvura, iyo inonyanya kusanganisira matanho matatu ekunyorova, de-agglomeration uye kudzikamisa kwezvikamu zvakapararira.Kunyorova (Wetting) zvinoreva nzira yekuwedzera hupfu zvishoma nezvishoma kumhepo yakaumbwa mumisanganiswa system, kuitira kuti mweya kana zvimwe zvitsvina zvakaiswa pamusoro pehupfu zvinotsiviwa nemvura.De-agglomeration inoreva kuparadzira akaunganidzwa ehukuru hudiki kuita zvidimbu zvidiki nenzira dzemakanika kana dzinokura zvakanyanya.Kudzikamisa kunoreva kuve nechokwadi chekuti zvidimbu zvehupfu zvinochengetedza kupararira kweyunifomu kwenguva refu mumvura.Zvinoenderana nenzira dzakasiyana dzekuparadzira, inogona kukamurwa kuita kupararira kwemuviri uye kupararira kwemakemikari.Ultrasonic dispersion ndiyo imwe yenzira dzekupararira kwemuviri.
Ultrasonic dispersionnzira: Ultrasound ine hunhu hwepfupi wavelength, inenge yakatwasuka kupararira, uye nyore simba rekuisa.Ultrasound inogona kuwedzera kemikari yekuita chiyero, kupfupisa nguva yekuita, uye kuwedzera kusarudzwa kwemaitiro;inogonawo kukurudzira maitiro emakemikari asingakwanisi kuitika pasina kuvapo kwemafungu e ultrasonic.Ultrasonic dispersion ndeyekuisa yakananga iyo particle kumiswa kuti igadziriswe mumunda we-super-generation, uye kuibata nemasaisai e ultrasonic akakodzera frequency uye simba.Iyo inzira yepamusoro-soro yekuparadzira.Iyo nzira ye ultrasonic dispersion inowanzo tenda kuti ine hukama ne cavitation.Kupararira kwemafungu e ultrasonic kunotora svikiro semutakuri, uye pane imwe nguva inotsinhanisa yezvakanaka uye zvisina kunaka kudzvinyirira panguva yekupararira kwemafungu e ultrasonic mukati.Iyo yepakati inosvinwa uye inodhonzwa pasi pezvipingamupinyi zvakanaka nezvakaipa.Kana mafungu e ultrasonic ane yakakura zvakakwana amplitude akaiswa kune yemvura yepakati kuchengetedza inogara yakakosha molecular chinhambwe, iyo yemvura yepakati inopwanya uye kugadzira microbubbles, iyo inowedzera kukura kuita cavitation bubbles.Kune rumwe rutivi, mabhuru aya anogona kunyungudutswa zvakare musvikiro remvura, kana kuti anogona kuyangarara achinyangarika;vanogonawo kudonha kubva kune resonance chikamu che ultrasonic munda.Kudzidzira kwakaratidza kuti pane yakakodzera super-chizvarwa frequency yekupararira kwekumisikidzwa, uye kukosha kwayo kunoenderana nekukura kwechikamu chezvimedu zvakamiswa.Nechikonzero ichi, nerombo rakanaka, mushure menguva yekuzvarwa kukuru, mira kwechinguva uye uenderere mberi nekuzvarwa kuti urege kupisa.Kutonhodza nemhepo kana mvura panguva yekuzvarwa kukuru zvakare inzira yakanaka.
